All Implemented Interfaces:

CollectionMeasurement, Measurement

public class NameListMeasurement

extends MeasurementBase

implements CollectionMeasurement

Accumulates a set of values. Its numerical value is the cardinality (i.e., size) of the set. OOMetrics uses it to keep track of dependencies.

This is the syntax for initializing this type of measurement:

  <init>
      [SET | LIST]
  </init>
  

Defaults to SET (i.e., does not count duplicates).
